SPECIFICATION forming part oi Letters Patent No. 393,355, dated November 2'7 1888,

Application filed August 24, 1887. Serial No. 247.752. (ModeL) To aZZ whom it may concern.-

' Be it known that I, ARTHUR W. BURNHAM, of Gardiner, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Mop-Wringers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention'relates to an improvement in mop-wringers, and particularly to a class in which the wringing device is made a fixture to a scrub pail or bucket.

The object of my invention is to produce a nrop-wringer of the class above indicated that will be compact in form, reliable in action, and that may be produced at a low cost.

With this object in view my invention consists in certain features of construction and combinations of parts, that will be hereinafter more fully described, and pointed out in the claims.

Referring to the drawings, making apart of this specification, Figure l is a side elevation of the working mechanism and its supporting tripodstand in position in a pail, the sides of the latter being broken away to show the device which exhibits the wringing-rollers at their point of farthest separation. Fig. 2 represents a side elevation of the wringing-machine in position in a pail, the latter being broken in section to show the wringer apparatus, which latter is in closed adjustment. Fig. 3 is a front elevation of the wringing device with the body of the pail removed. Fig. 4 is a longitudinal section of the base-plate. Fig. 5 is a detached view of the rock-arm. Fig. 6 is a plan view of the base-plate, showing standard K in section.

The wringing mechanism is placed in a water-pail, B, and is connected to a tripod, A, which is adapted to fit upon the under side of the pail and afford a support to it. The tripod A has two laterally diverging legs, A, attached to an enlarged joiningplate, A". This plate A is widened, and has a flat top surface that extends a proper distance to afi'ord a support for the pail-bottom in conjunction with the horizontalupper surfaces of the legs A. The third leg, A, of the tripod A is extended in line with the terminal end of the joiningplate A and is an integral extension of the same. The leg A is made to extend toward the front or nearest side of the pail to the op erator, and is projected horizontally a greater length than the legs A fora purpose that will be made apparent.

Upon the inner surface of a pail, B, that is properly placed on the bearing-faces of the legs A, plate A and extended leg A of the supporting tripod A, the base plate B is seated. A bolt, a, is made to project from the lower surface of the base-plate just mentioned to penetrate a hole of proper size made in the bottom of the pail B to receive it, and this bolt is also inserted through a hole in thejoining- 'plate of the tripod A to afford means for securely attaching the tripod, pail, and baseplate together by the proper adjustment of a nut, a, on the threaded end of the bolt, the nut bearing firmly against the lower surface of the tripod about at the point of junction of. the three legs of this tripod A.

The base-plate B consists of a fiat piece of metal, preferably of a rectangular form-that is, perforated at proper points, 1 2, to lighten it-and has vertical ribs 3 4 formed integral with its side edges. At the forward end, or end nearest the leg A of tripod A this baseplate is provided with lugs 5 6, which are notched to form a half-round groove across their top faces. These grooves 7 8 are from their location parallel to the side surfaces of the ribs 3 4 of base-plate B. At the rear or opposite end of the base-plate B there are two ears, 9 10, made integral with the terminal ends of the ribs 3 4, of this plate,and outwardly projected from them at right angles to the side surfaces of the ribs. The ears 9 10 are perforated through their bodies, these holes being aboutin line with the grooves 7 8, that are cut in the top edges of the lugs 5 6, that project from the front end of the base-plate B.

Thewire bail-clamps F Fare intended to be supported by their ends in swinging adjustment with the sides of the base-plate B. To effect this the rear ends, I), of these clamps are bent to enter the holes in the ears 9 10 at rear end of base-plate B, and the forward ends of these bail-clamps are bent nearly at a right angle to the forward vertical 1imbs,h",of these clamps, so as to provide journals 0 from the wire bodies of the clamps that rest in the grooves 7 S in lugs 5 6 and allow the clamps h F to rock on these points of support. The projecting ends of the bail-clamps 1* F, that are integral extensions of the journals 0 of said clamps, are bent and wound around the outer ends of these journals to produce spiral springs c, which springs are intended to afford a lim ited yielding action to the clamps F F when they are in use.

Upon the forward end of the base-plate B there are two lugs, 11 12, made to project from the sides of the base-plate B, that are similar in form to the lugs 5 6, previously described. They are situated near to these latter-named projections 5 G, and are parallel to them. The lugs 1.1 12 are so relatively located as to allow the grooves on their lower surface to receive the wire journals of the bail-clamps F F, and by contact therewith prevent upward dis placement of these swinging clamps.

Upon the upper surface of the forward end of the base-plate B, at the corners of the same, two vertically-projecting limbs, 11, are formed integrally with it. These are intended to brace and re-enforcc both of the upright parallel standards G. The standards G just mentioned are provided each with a lip or short lateraltlange, g,which latterhave bearing contact with the sides of the vertical limbs d, and partially embrace the same to lock the limbs and standards together, this look being rendered secure by the proper adjustment of the nuts h, which are adapted to fit the lower threaded ends of these standards G, the rounded and threaded ends it of the standards passing through perforations in the body of the baseplate B made to receive them. The standards G are preferably given a forward inclination, so as to conform substantially to the flaring innersurface of thepail B, which will economize space in the pail and allow a wider divergence of the swinging roller J. The standards G are braced by the cross-bar c, which is preferably cast integral with the standards. At the upper terminations of the standards an integral roller supporting bracket, G", is located. This bracket lies in a plane parallel to the bottom of the pail B, and has its ends G bent at right angles to the main portion to receive between them the ends of the roller I.

The roller I is preferably made of wood of proper hardness, and has wear-plates Iat'tixed to its ends, these plates being perforated ecntrally to receive the bodies of stout screws f, which are inserted through holes made in the ends G of the bracket G these screws affording cheap and reliable pintles or journals for the roller I, the wear-plates 1 giving support to the screw-bodies and preventing them from becoming loose or the roller ends being worn away. A mating roller, J, of the samelength and diameter as the roller I, is mounted upon the single standard K, the upper end of which is constructed with a bracket, K, of similar form to that of the bracket G", which bracket K is attached to afford revoluble support to the roller J by screws t, which penetrate the ends of this roller, the ends of the roller J having wear-platcs 7;, when wearing away to prevent wearing away of the ends, these plates It being duplicates of the plates 1, that protect the ends of stationary roller I. The swinging standard K has a bifurcated foot-piece, K", the parallel jaws K" of which are such a proper distance apart as to loosely bear with their inner sides against the outer surface of the vertically-projecting cars at, to which they are pivoted, and which lugs are made integral with the upper edges of the ribs 3 4 of the baseplate B.

The forward end of the rocking bar L cX- tends between the parallel standards G and projects slightly forward of the same. It is slotted at this end, and has two eyes, 0, formed from theparallel strips of material left. These eyes or perforated bosses are adapted to receive between them the lower end of thelinkbar M, which is pivoted to them, and also at its upper end to the rock-arm M. The rockarm M is provided with two parallel jaws, 1, near its center (considered lengthwise) to engage the top end of the link-bar M, and has its end that connects to the bracket G made T- shaped to engage with it by a peculiar hinged joint, that will now be described.

Upon the top surface of the bracket G two hooks, q, are formed, that project theircurved free ends rearwardly. The space between these hooks q is sufficient to allow them to receive the notched ends of the integral bar- M" of the T-shaped head formed on the rock-arm M. The portions of bar M which engage the hooks q are rounded to producejournals, and the adjacent projections, q, act as guards to prevent the disconnection of the bracket and rock-arm, while a rolling connection is established between these pieces, and the rock-arm M. is allowed to vibrate when pulled downwardly by its outer end. The outer-end, M, of the roc -arm M is forked and has the two limbs r of the bifurcated end turned up to form retainingguards.

A depending treadle-rod, N, has its top end made T-shaped to enter the slot between the upturned limbs r of the crotchcd outer end of rock-arm M, and engage with its cross-bar s the curved limbs r, which latter serve to hold the parts in hinged engagement and permit the vertical depressionof the rod N.

A foot-plate or treadle-piece, N, is adjustably attached to the treadle-rod N by a setscrew, I, so as to permit the foot-plate to be properly adjusted for height and allow an increase of travel to be given to the treadle, if necessary, to more forcibly close the swinging roller J against the revolving but stably-located roller I.

A guided-0d, O, is erected from the top of leg A of the tripod A, and is made to enter a perforated ear formed on the side of the boss IIO t of the foot-plate N, and thus steady the treadle-rod and its foot-plate when it is operated by the application of the foot of a user of the device.

The rear end of the rocking bar L is projected beneath the standard K and has bearing contact with the depending short arm I, that is an integral projection from the bifurcated lower end of this swinging standard.

Upon the top surface of the rocking bar L the curved plate-spring R is affixed by one end, the free end B of the same being made to forcibly bear against the swinging standard K and hold it rearwardly projected when the device is not in use as a wringer. This action of the spring R will seat the bifurcated lower end of the standard K upon the adjacent top edges of the ears 9 10, that project from the side ribs of the base-plate 'B, and the rear roller, J, that is supported by the standard K, will be separated sufiiciently from the other roller, I, to allow a mop-cloth to be freely inserted between the rollers into the water with which the pail is partially filled.

The forward arms, 0' of the wire bail-clamps F F, that are extended beyond the spiral springs c, are bent inwardly at right angles to the journals 0, and arcmade to engage the lower end of the link-bar M, they being inserted in adjacent holes made through the lower portion of thelink-bar that projects be low its point of hinged connection with the rocking bar Il- This connection of the bailclamps F F with the link-bar M will cause the depression of the foot plate N to forcibly close the bail-clamps toward each other, and at the same time force forward the swinging standard K and its roller J, so that the mop-cloth that has been introduced between these two sets of compressors and first washed in the contained water in the pail B may be clamped sidewise by the clamps F F, and also by the forward movement of roller J. The simple withdrawing of the mop from the pail and a compression of the clamps F F and roller J by pressure of the foot of the operator upon the foot-plate N will effectually remove all the water from the cloth, as the gathering action of the bail-clamps F F will force the cloth into a compact mass and strip the'water from the cloth, while the rollers perfect the wringing operation.

It should be stated that the bearing ends of the legs of the tripod A are provided with elastic base-blocks '1, upon which the waterpail and entire devieearesupported. Thisprovision will prevent the metal feet from scratching a floor, and the extended bearing afforded by the tripod will support the device. firmly and allow it to rest secure upon any uneven surface it may be placed upon. The gum blocks T are inserted in vertical perforations It, made in the feet of the tripod.

Slight changes might be made in the construction of this device without exceeding the scope of my invention; hence I do not limit myself to the exact forms herein shown; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1.
